The converted label is later\nexposed through ntfs3_label_show() using %s, but utf16s_to_utf8s() only\nreturns the number of bytes written and does not add a trailing NUL.\n\nIf the converted label fills the entire fixed buffer,\nntfs3_label_show() can read past the end of sbi->volume.label while\nlooking for a terminator.\n\nTerminate the cached label explicitly after a successful conversion and\nclamp the exact-full case to the last byte of the buffer.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
